Rare Metals, Volume 45, Issue 5, May 2026.ABSTRACT Aqueous zinc‐ion batteries are plagued by anode challenges such as dendrite growth and corrosion, which stem from intrinsic surface heterogeneity. Although constructing a homogeneous interfacial layer is a promising strategy, conventional electrolyte additives often suffer from incomplete or unstable coverage.

Shuitu Baochi Xuebao, 2011 土壤侵蚀过程中,土壤团聚体的迁移反映了团聚体的破碎程度及径流的搬运能力,直接影响着侵蚀强度。以东北典型薄层黑土区耕层土壤为研究对象,采用模拟降雨试验方法,研究裸露休闲、纱网覆盖与秸秆覆盖3种地表条件下不同粒级(>5mm,2～5mm,1～2mm,0.5～1mm,0.25～0.5mm和秸秆覆盖;(3)纱网覆盖和秸秆覆盖下的团聚体粒级分布与裸露休闲的相比,差异较为明显的均是秸秆覆盖。

World Water Policy, Volume 12, Issue 2, May 2026.ABSTRACT This paper explores the unequal water supply infrastructure in Khulna city's informal settlements, focusing on the largest slum, Rupsha. It investigates both formal and informal water governance, examining the roles of various actors, their decision‐making processes, and the challenges these settlements face in accessing water.

Methods in Ecology and Evolution, Volume 17, Issue 4, Page 1143-1160, April 2026.Abstract DNA barcode‐based species identification has become pivotal in biodiversity research. Current barcoding‐based deep learning methods have advantages in species identification but exhibit significant limitations. By using COI barcoding alone, previous studies were unable to fully capture species identification features. Prior methods showed that

Shuitu Baochi Xuebao, 2023 为了分析植被覆盖对黄土高原坡面水土流失的影响,量化土壤侵蚀的植被覆盖阈值,基于模拟降雨数据分析了植被覆盖对土壤侵蚀的作用机制,利用绥德、西峰、天水等黄土高原高原典型地区的野外径流小区定位观测资料,探讨了不同覆被类型下植被覆盖控制径流和土壤侵蚀的有效性,确定了不同覆被类型下植被覆盖调控径流和防治土壤侵蚀的植被覆盖下限阈值和上限阈值。结果表明:(1)植被覆盖度的提高增加了土壤入渗、减少了径流量、延缓了径流流速、增加了土壤抵抗侵蚀的能力。(2)坡面径流量随植被覆盖度呈幂函数或指数函数下降 ...

Automating the analysis of public saliency and attitudes toward biodiversity from digital media
Conservation Biology, Volume 40, Issue 2, April 2026.Abstract Measuring public attitudes toward wildlife provides crucial insights into human relationships with nature and helps monitor progress toward Global Biodiversity Framework targets. Yet, conducting such assessments at a global scale presents challenges.

Shuitu Baochi Xuebao, 2017 为研究植被覆盖度对紫色土坡面侵蚀过程的影响，探讨有效控制水土流失的坡面植被临界盖度问题，利用人工模拟降雨试验与室内分析相结合的方法对紫色土坡面侵蚀过程进行分析。结果表明：（1）总体上，紫色土坡面产流量随植被覆盖度的增大而减小，二者之间呈现线性负相关，但是植被覆盖度在25%以下，径流量变化不明显，植被覆盖度达75%时，径流量处于较低的稳定值，明显低于植被覆盖度0%，25%，50%；（2）坡面侵蚀泥沙量随植被覆盖度的增加而减少，二者呈现二次项相关（R2=0.99），植被覆盖度25%以下对坡面减沙起到重要作用，

Shuitu Baochi Xuebao, 2000 我国覆膜稻栽培研究始于１９９６年，但迄今都为地膜单元覆盖，水稻秸秆＋地膜二元覆盖旱作栽培效应的研究结果表明，秸秆＋地膜二元覆盖旱作稻田土壤变温幅度降低，水分散失减少，结构改善，养分积累增加；水稻无效分蘖减少，生育转变提前，灌浆结实期延长，穗大粒多，千粒重高，增产效果显著，稻谷产量较地膜覆盖，秸秆覆盖，露地旱作栽培分别增产１０．３％，８．９％，２３．２％。

Shuitu Baochi Xuebao, 2017 为探究不同覆盖措施对养分流失及其粒径分布的影响，采用人工模拟降雨试验的方法，模拟了不同雨强（30，60 mm/h）和不同覆盖物（枯落物、砾石）下，不同覆盖度对褐土坡面养分流失的影响，并对侵蚀土壤的粒径分布、养分流失浓度进行了分析。研究表明：（1）覆盖措施能够有效减少土壤流失，250 g/m2的枯落物和盖度为50%的砾石覆盖可减少91%~98%和68%~91%的土壤流失。（2）褐土坡面下，被侵蚀土壤中有机质、速效氮、速效磷的浓度基本不随覆盖条件的变化而变化 ...
